【摘要】：針對傳統(tǒng)及現(xiàn)有水生態(tài)足跡理論及其模型存在的缺陷與不足,本文提出了基于生態(tài)系統(tǒng)供給及凈化服務功能的貴州省水生態(tài)占用概念與模型,將其劃分為生物生產(chǎn)和非生物生產(chǎn)的水生態(tài)占用兩部分,建立水產(chǎn)品、水資源、水環(huán)境3類賬戶,并在此基礎(chǔ)上以2000—2014年的貴州省為例進行計算分析,結(jié)果表明:(1)水產(chǎn)品賬戶中,貴州省水產(chǎn)品消費的水生態(tài)占用總體呈上升趨勢,水生態(tài)承載力波動變化較小,水產(chǎn)品消費呈生態(tài)赤字狀態(tài),且其生態(tài)壓力較大;(2)水資源賬戶中,貴州省淡水資源的水生態(tài)占用整體呈逐漸上升趨勢,水生態(tài)承載力則呈明顯波動的趨勢,且變化幅度較大,淡水資源消費處于生態(tài)盈余狀態(tài),且其與水生態(tài)承載力的變化態(tài)勢一致,淡水資源消費的生態(tài)壓力較小;(3)水環(huán)境賬戶中,水環(huán)境生態(tài)壓力主要來源于氮污染,2000—2010年消納污染的水生態(tài)占用變化不大,2011—2014年波動較大,歷年生活水污染賬戶值均大于工業(yè),今后要注重加強生活水污染防治,消納污染的水生態(tài)承載力呈波動變化的趨勢,水環(huán)境處于生態(tài)赤字狀態(tài),且其生態(tài)壓力較高;(4)與現(xiàn)有生態(tài)足跡模型的比較分析可知:該模型核算更為全面;不考慮均衡因子,并以最大水生態(tài)壓力指數(shù)來評價區(qū)域水生態(tài)系統(tǒng)所承受的壓力狀態(tài)具有合理性,更能準確反映貴州水生態(tài)的實際情況和水生態(tài)文明建設的需要.
[Abstract]:In view of the shortcomings and shortcomings of the traditional and existing water ecological footprint theory and its model, the concept and model of the ecological occupancy of Guizhou Province Based on the ecosystem supply and purification service are proposed, which are divided into two parts of the ecological occupation of biological production and non biological production, and the 3 types of accounts of aquatic products, water resources and water environment are established. On the basis of this, the accounts of Guizhou province from 2000 to 2014 were calculated and analyzed. The results showed that: (1) in the account of the aquatic products, the water ecological occupancy of water products consumption in Guizhou province was generally on the rise, the fluctuation of water ecological carrying capacity was small, the consumption of aquatic products was ecologically red, and its ecological pressure was large; (2) the water resources account was expensive. The water ecological occupancy of the fresh water resources in the state is increasing gradually, and the water ecological carrying capacity is obviously fluctuating, and the change range is large. The consumption of fresh water resources is in the ecological surplus state, and it is consistent with the change of water ecological carrying capacity, and the ecological pressure of fresh water consumption is small. (3) water environment accounts, water environment students. The main source of state pressure is from nitrogen pollution. The ecological occupancy of water pollution from 2000 to 2010 has not changed much. The fluctuation of the water pollution accounts from 2011 to 2014 is larger than that of the industry. In the future, the prevention and control of water pollution should be strengthened, and the ecological carrying capacity of water pollution is fluctuating, and the water environment is in the state of ecological deficit. And its ecological pressure is high; (4) compared with the existing ecological footprint model, it can be found that the model is more comprehensive, and it is reasonable to evaluate the pressure state of the regional water ecosystem without considering the equilibrium factor and the maximum water ecological pressure index, and can accurately reflect the actual situation of Guizhou water ecology and the construction of water ecological civilization. The need to set up.
